Answer:
( 89-5) *5 + ( 35+4)*5
84*5+ 39*5
Step-by-step explanation:
The cost for the hotel will be 89 -5 =84 dollars per night if she pays in advance
The cost of the car is ( 35+4) = 39 per day
She is staying 5 days
( 89-5) *5 + ( 35+4)*5
84*5+ 39*5
That’s is so impressive dude ngl

Answer: 482 cars
Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of population proportion.
= Two-tailed z-value for (significance level).
E= Margin of error .
Given : Margin of error = 3% = 0.03
Confidence level = 90%=0.90
By z-value table :
To gauge the size of the problem, the agency first picks 40 cars and finds 8 with faulty emissions systems.
Then , the prior estimate of population proportion of faulty emissions systems =
Then, the required sample size would be :
Hence, 482 cars should be sampled for a full investigation.
Answer:
Step-by-step explanation:
so we know that a triangle degrees have to add up to 180 in the inside right? So we know c is 90 and so you need to find A and B. The left over degrees you have is 90 so the sum of B and A would have to be 90, thats all i can help you with sorry.
